Growth and Foliar Alkaloid Content of Clitoria ternatea under Different Irrigation Frequencies
Full text linkClitoria ternatea is widely used in tropical livestock farming. This study evaluates the agronomic performance and alkaloid content of C. ternatea under different irrigation frequencies in protected cultivation. A randomized block design with controlled manual irrigation was implemented with five treatments, four replicates, and five experimental units per treatment. Treatments included daily irrigation (T0), irrigation every two days (T1), every three days (T2), every four days (T3), and every five days (T4). We evaluated plant height, leaf and internode number, leaf area, green and dry matter yield, and alkaloid content. Irrigation every three or four days generally resulted in the highest values for the measured variables compared to the control. Reduced irrigation frequency affects the agronomic performance of C. ternatea in protected cultivation. Agronomic indicators were highest under irrigation every three or four days. Alkaloid content did not vary with irrigation frequency.
Highlights:
Clitoria ternateais widely used in tropical livestock farming due to its adaptability, productivity, and nutritional value.
Thestructured design with controlled manual irrigation had five treatments, four replicates and five experimental units, totalizing 100 plants.
Maximum plant height was achieved when Clitoria ternateareceived irrigation every four or five days, with T4 reaching 48.50 cm at 50 days
Leaf number increased as plants matured, with the highest value recorded in T3 (48 leaves at 50 days).
Irrigation every 2 days increases alkaloid content and plant yield.Clitoria ternatea is widely used in tropical livestock farming.

Conflictos de interés en la cadena de valor del reciclaje: Oportunidades de políticas públicas para una gestión inclusiva
Full text linkEste artículo examina los conflictos de interés que enfrentan los recuperadores urbanos en la cadena de valor de reciclaje de la ciudad de Córdoba (Córdoba, Argentina), con el fin de aportar a la discusión sobre economía circular e inclusión social. Se realizó un estudio cualitativo a partir de fuentes documentales y 37 entrevistas semiestructuradas a informantes clave de la cadena. Se identificaron cuatro tipos de conflictos: requisitos de la industria transformadora, marco institucional, percepciones sobre el rol de los recuperadores e impactos ambientales. Estas tensiones limitan la participación de los recuperadores en la cadena de valor y obstaculizan mejoras en términos económicos, sociales y ambientales. A partir de este análisis, se proponen cuatro lineamientos para orientar las políticas públicas hacia una economía circular más inclusiva: intervención en los mercados de materiales reciclables, adecuación del marco normativo, promoción de sinergias y objetivos comunes, y gestión del impacto ambiental de la cadena

Effects of Climate Change on Nine Rainfed Zea mays Races in Chiapas, Mexico
Full text linkMaize cultivation (Zea mays) is essential for Mexico from a nutritional, cultural and economic perspective. Scientific literature ignores the impact of anthropogenic causes of climate change on rainfed cultivation of Z. mays in Chiapas, Mexico, one of the poorest states in the country. Therefore, we modeled the feasibility of rainfed cultivation for nine races of rainfed maize for the years 2060 and 2100. The MaxEnt 4.4.4 algorithm modeled maize cultivation under two scenarios (4.5 and 8.5) for 2060 and 2100. Model inputs were 12 bioclimatic variables, 3 climatic variables, and 1 elevation variable. All layers were obtained from the WorldClim 2.1 project. By 2060, the suitable area for rainfed cultivation of the nine Z. mays races would drastically decrease under both modeled scenarios. By 2100, this area will decrease for seven races, and disappear for the Olotillo and Olotón races. To the best of our knowledge, this is the first study providing fundamental information on how climate change will negatively impact the nine Z. mays races in Chiapas, Mexico. This enables the development of sustainable management protocols or conservation strategies.
Highlights:
The MaxEnt algorithm proved very useful in modeling the effect of climate change on Zea mays.
By the year 2060, the viable rainfed cultivation area of the nine mays races will drastically decrease under climate change scenarios 4.5 and 8.5 in Chiapas, México.
By the year 2100, the viable rainfed cultivation area of seven mays races will drastically decrease under climate change scenarios 4.5 and 8.5, while Olotillo and Olotón maize races will completely disappear in Chiapas, México.
“Maximum temperature of the warmest month” (Bio 5) was the variable with more contribution in 2060 (74% and 92.6%, for 4.5 and 8.5 scenarios, respectively) and in 2100 (59.3% and 89.1%, for 4.5 and 8.5 scenarios, respectively).Maize cultivation (Zea mays) is essential for Mexico from a nutritional, cultural and economic perspective.

Enterococcus gallinarum CRL 1826 as a Probiotic for Ranaculture: in vitro Safety, Technological, and Physiological Properties:
Full text linkThis study aimed to progress in designing a probiotic containing autochthonous Enterococcus gallinarum CRL 1826 for application during the life cycle of Lithobates catesbeianus in hatchery conditions. We assessed bacterial resistance to chemotherapeutics used in ranaculture, the presence of genes encoding virulence factors (VF) and vancomycin resistance, and bacterial survival and maintenance of beneficial properties after freeze-drying and storage. The strain exhibited resistance to antiseptics, sensitivity to most chemotherapeutics, presence of vanC, and absence of VF genes. It demonstrated resistance to freeze-drying and the highest survival when using skim milk+sucrose and storage at 4°C for 24 months. It also displayed bacteriocin activity against Listeria monocytogenes. Pre-lyophilized and lyophilized cultures grew/resisted individual gastrointestinal conditions and simulated gastrointestinal digestion, keeping bacteriocin activity and surface properties. For the first time, we demonstrated that E. gallinarum CRL 1826 is a safe bacterium with technological and physiological properties that would allow bullfrog gut colonization. These studies are essential for progressing towards selecting E. gallinarum CRL 1826 as a probiotic to prevent epizootics during bullfrog breeding and control foodborne bacteria, potentially improving growth performance of L. catesbeianus.
Highlights:
Enterococcus gallinarum CRL 1826 was sensitive to chemotherapics used in ranaculture.
The strain did not display virulence and transferable vancomycin resistance genes.
The dried strain showed great survival and bacteriocin activity for 24 months’ storage.
The LAB resisted the gastrointestinal conditions and kept its bacteriocin activity.This study aimed to progress in designing a probiotic containing autochthonous Enterococcus gallinarum CRL 1826 for application during the life cycle of Lithobates catesbeianus in hatchery conditions.

Uma borda sobre a terra, a ambivalência da fronteira na literatura de Fabián Severo
Full text linkIn this article, dedicated to the novel Sepultura (2020) from the writer Fabian Severo, we reflect about the frontier as a literary topus. Besides the access difficulties to the publishers that the uruguayan writer faced with an insertion of portunhol in his literary work, since his first publish in 2010, he obtained recognition by part of the critics, having ever received several prizes. Generally, the critics highlight that the writer carries the voice and the memory of an interstitial region between Uruguay and the south of Brazil. Considering these aspects, we reflect about the cultural landscape created by Fabian Severo's novel from a critic perspective that joins geography and literature. So, the theoretical subsidies, which base our reflection, are especially, besides the studies of narratology, contribution of the book Del topos al logos Propuestas de geopoética (2006) from Fernando Aínsa and of the essay Frontera, naciones y región (2004) from Alejandro Grimson. Finally, based on the fundaments of geopoetic we understand how portunhol turns into a river of words and images which irrigates the culture of the region and how this aesthetic option is associated to the ambivalence senses of frontier present in the literature of the young frontier writer.Este artículo dedicado al libro Sepultura (2020) de Fabián Severo, reflexiona sobre la frontera como topus literario. Pese a las dificultades iniciales de acceder a editoras en consecuencia de la inserción del portuñol en su obra literaria, el escritor uruguayo obtuvo pronto reconocimiento por parte de la crítica y conquistó varias premiaciones en el ámbito literario. De modo general, la crítica señala que el escritor revela la voz y la memoria de una región intersticial entre Uruguay y el sur de Brasil. Considerando estos aspectos, desde a de una propuesta crítica que asocia geografía y literatura reflexionamos sobre el paisaje cultural creado por la novela de Fabián Severo. Por eso, los subsidios teóricos de este trabajo, además de los estudios de narratología, son, sobre todo, el ensayo Frontera, naciones y región (2004), de Alejandro Grimson y Del topos al logos. Propuestas de geopoética (2006), libro de Fernando Aínsa. Al final, a partir de los fundamentos de geopoética alcanzamos entender tanto la apropiación del portuñol, como si fuera un rio de palabras e imágenes que irriga a la cultura de la región, como los sentidos ambivalentes de la frontera que la literatura del joven escritor fronterizo revela.Neste artigo, dedicado ao romance Sepultura (2020) do escritor Fabián Severo, refletimos sobre fronteira como um topus literário.

Afinal, a partir dos fundamentos da geopoética alcançamos entender não só como portunhol torna-se um rio de palavras e imagens que irriga a cultura da região, mas também a ambivalência de sentidos de fronteira que perpassa a literatura do jovem escritor fronteiriço
Esconder la ética en el μῦθος. Ejemplaridad e imitación en la fábula “Zeus, Eros y los hombres” (or. 10) de Himerio
Full text linkThis article aims to examine the use of the so-called "etiological fable" by Himerius, a prominent rhetorician and educator, in one of his fragmentarily preserved Orationes (10, 40-60). We will explore the functions that the rhetor assigns to the μῦθος (as he calls it) of "Zeus, Eros, and Men," focusing on the ethical-exemplary dimension of the narrative and its subsequent classification as a fable. The way the story is articulated in the declamation allows us to conclude that it is not only used as an exemplum to educate the audience but also: i) rhetorically reflects on how μύθοι intertwine and juxtapose mythical, divine content with ethical teachings; ii) indicates its affiliation with Neoplatonic philosophy within a specific socio-political context; and iii) shares the rhetor's feelings to the departing student.Este artículo se propone examinar el uso de la denominada “fábula etiológica” por parte de Himerio, destacado rétor y educador, en una de sus Orationes conservadas fragmentariamente (10, 40-60). Problematizaremos cuáles son las funciones que el rétor otorga al μῦθος (tal como este lo denomina) de “Zeus, Eros y los hombres” atendiendo a la dimensión ético-ejemplar del relato y su clasificación posterior como fábula. El modo en que se articula el relato en la declamación permite concluir que no solo se utiliza como exemplum para educar a su audiencia, sino que a su vez: i) reflexiona retóricamente sobre la manera en que los μύθοι mezclan y yuxtaponen lo mítico, lo divino y la enseñanza ética; ii) marca su pertenencia dentro de la filosofía neoplatónica, en un contexto sociopolítico determinado y iii) comunica sus sentimientos al estudiante que se va
Infâncias Exiladas em Cuba Durante a Ditadura Chilena (1973-1990): Uma Análise das Marcas do Trauma Psicossocial em Dois Documentários
Full text linkThis study examines the processes of subjectivation of trauma in children exiled to Cuba during the Chilean civil–military dictatorship (1973–1990). The guiding question is: what psychic, social, cultural, and affective traces did exile leave on these childhoods, and how are they narrated in documentary cinema? The theoretical framework integrates contributions from psychoanalysis, Latin American critical psychology, and postmemory theory. The methodology consisted of discourse analysis of childhood narratives recorded in two documentaries: Los ojos como mi papá (1979) by Pedro Chaskel and El edificio de los chilenos (2010) by Macarena Aguiló and Suzana Foxley, addressing their processes of meaning-making as phenomena of social semiosis. The findings show that childhood exile trauma left psychic marks (affective, identity, and reparative registers, traversing the intergenerational dimension) and social marks (uprooting, community reconfiguration, cultural integration), in addition to processes of resignification and resilience. The study concludes that documentary cinema constitutes a key device for reconstructing children’s memories of exile, making visible their intergenerational transmission, and contributing to strategies of symbolic reparation and the construction of historical memory.Este trabajo estudia los procesos de subjetivación del trauma en infancias exiliadas en Cuba durante la dictadura cívico-militar chilena (1973–1990). La pregunta que orienta el estudio es: ¿qué huellas psíquicas, sociales, culturales y afectivas dejó el exilio en estas infancias y cómo son narradas en el cine documental? El marco teórico integra aportes del psicoanálisis, la psicología crítica latinoamericana y la teoría de la postmemoria. La metodología consistió en un análisis del discurso de infancias registrado en dos documentales: Los ojos como mi papá (1979) de Pedro Chaskel y El edificio de los chilenos (2010) de Macarena Aguiló y Suzana Foxley, abordando sus procesos de significación como fenómenos de semiosis social. Se concluye que el trauma exiliar infantil dejó marcas psíquicas (registros afectivos, identitarios, y de reparación, que atraviesan lo intergeneracional) y sociales (desarraigo, reconfiguración comunitaria, integración cultural), además de procesos de resignificación y resiliencia. Se concluye que el cine documental constituye un dispositivo clave para la reconstrucción de memorias infantiles del exilio, visibilizando su transmisión intergeneracional, y aportando a estrategias de reparación simbólica y construcción de memoria histórica.Este estudo analisa os processos de subjetivação do trauma em crianças exiladas em Cuba durante a ditadura cívico-militar chilena (1973–1990). A pergunta que orienta a pesquisa é: quais marcas psíquicas, sociais, culturais e afetivas o exílio deixou nessas infâncias e como elas são narradas no cinema documental? O referencial teórico integra contribuições da psicanálise, da psicologia crítica latino-americana e da teoria da pós-memória. A metodologia consistiu na análise do discurso de infâncias registradas em dois documentários: Los ojos como mi papá (1979), de Pedro Chaskel, e El edificio de los chilenos (2010), de Macarena Aguiló e Suzana Foxley, abordando seus processos de significação como fenômenos de semiose social. Conclui-se que o trauma do exílio infantil deixou marcas psíquicas (registros afetivos, identitários e de reparação, que atravessam o plano intergeracional) e sociais (desenraizamento, reconfiguração comunitária, integração cultural), além de processos de ressignificação e resiliência. O estudo aponta que o cinema documental constitui um dispositivo fundamental para a reconstrução das memórias infantis do exílio, tornando visível sua transmissão intergeracional e contribuindo para estratégias de reparação simbólica e de construção da memória histórica
